Hi, I have downloaded G_Tech_Firmware_Update_Utility_Universal_v2.zip und it intalled. The App is not finding my G-Drive. It is connected by firewire and it´s the only one.The Problem because I want to update the firmware is, that TimeMachine sometimes does not find the drive. But if, it is working fine.Any hints?Merry Christmas, Ulli

Thanks for posting. The firmware update is for g-drive generation 5 which have usb 3 and firewire 800. Is the drive connected directly to the computer or is it through a hub of some kind? Have you confirmed that the computer can see the drive at all? Does the drive mount? If not does it appear in disk utility and or system report? If you can't see the drive from any of these it is not merely a firmware issue.

Okay. My G-Drive is 2Tb. I don't know which generation it is. I do see my drive every where in my system. Only TimeMachine tells me (sometimes) it cannot backup because the drive ist write protected, which is it definitely not. Regards Ulli

When you get the error see if you can copy a file to in manually. If you are able to the issue with with time machine. If you can't then it may be the drive. If you have usb 3 and firewire 800 it is a generation 5. If you have usb 2 and firewire 800 and esata then it is generation 4.

After longer time without using the G-Drive it disappears in the finder. Also Time Machine cannot find it. If I go and make a check with disc-utility there are no erros and the disc works perfekt. But I still cannot see it in the finder!

When this occurs and you see it listed in disk utility does it list as mounted or unmounted? This is a very strange occurrence. One thing I might suggest is to reset your smc and pram on your computer. It could be something within one of those causing the instability. If it persists after that we could see about replacing the drive under warranty.
